Abstract (en)
The invention lies in the field of the handling of a continuous flow (2) of covers (3), each comprising a middle portion (4) and a peripheral edge (5) extending around it asymmetrically in relation to the main plane, the main planes of which covers extend perpendicularly to the conveying direction (6), while the nominal orientations of the covers in the conveying direction are all the same. When transporting such covers in a continuous flow it is of essential importance for the processing thereof that all the covers have the same orientation. It can happen however that because of a disturbance a cover will from time to time display an opposite orientation. This can be very inconvenient for the further, particularly automatic, handling of the covers and can cause disturbances. Therefore until now the flow of covers has been visually inspected and an opposite oriented cover removed from the flow. The object of the invention is to have such an inspection take place automatically. For this purpose the invention provides a device for removing individual covers from a continuous flow of covers, each consisting of a middle portion and a peripheral edge extending around it asymmetrically in relation to the main plane, the main planes of which covers extend perpendicularly to the conveying direction, while the nominal orientations of the covers in the conveying direction are all the same and the said individual covers are oppositely oriented in relation to the nominal orientation, which device comprises: a conveyor (7) for transporting the covers (3, 3') in a continuous flow, a detector (8) placed adjacent to the conveyor (7) for distinguishing an oppositely oriented cover (3'), and an ejector (9) for removing from the flow (2) a detected oppositely oriented cover (3').
